Vannevar Bush
The first modern analog computer, the Differential Analyzer could solve certain classes of differential equations.
Vannevar Bush’s differential analyzer, developed at the Massachusetts Institute of Technology in the early 1930s, was an electromechanical analog computer designed to solve differential equations.12
The machine relied on several key mechanical components to perform calculations:
- Integrators: These were the core of the device, consisting of replaceable shafts, gears, wheels, and disks.1
- Integration Mechanism: Integration was specifically carried out using a knife-edged wheel that rotated at a variable radius on a circular table.2
- Gears: Sets of gears were used to perform addition and multiplication by processing values represented by shaft motion.2
These individual mechanical integrators were interconnected to solve complex mathematical problems, though the device required significant manual setup to operate.12
